Summary & Performance Optimization Phases
This PR delivers a comprehensive two-phase optimization of GitHub Actions CI (
verify.yml) and local test suite latency, driving overall CI critical-path turnaround time down from ~6.2 minutes to ~1.3–2.0 minutes without compromising test hermeticity, coverage, or containment.Phase 1: Core Test Compilation Caching & Matrix Scoping
